AUTOMOB ILE-TIRE Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed September 27, 1907. Serial N o. 394,782.

To all whom it may concern.'

Be it known that I, WILLIAM MLLER, a citizen of the United States, residing at No- 612 North Fifty-sixth street, in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Atomobile'l`ire, of which the icllewing is a speciiication.

My invention relates to automobile tiresl and my ob'ect is to provide a tire which shall combine the resilient qualities of the pneumatic tire with the durability of. the solid rubber or cushion tire. This I accomplish by the means herein described and shown in the accompanying drawings, in which- 'Figure l is a side View of an automobile whedl equipped with my improved tire. Fig. 2 is an en arged view in cross 'section ona line 272, showing the tire and the manner in which it is mounted in the rim 'of the wheel, and Fig. 3 is an enlarged view in crosssection on a line 3-3, showing the the, and therim at the juncton of a s oke therewith, showing the manner in whic the rim is split to admit of the insertion of the tire. Y In Fig. 2, the tire 1, which may' be of rubber or any suitable composition, is formed with a relatively circular or elli tical body, T e neck and by the enlargement of the base fwithin the sheath and by the pins or bolts 3 which pass through both tire and sheath at suitable in` tervals.

Thesplit rim 4, 4 is formed with jaws, as shown in Figs. 2 and 3, which clasp the neckand base of the tire-sheath in such wise asY to admit a vertical play of the latter therein, as hereinafter described.. The wheel rim is provided with the spring chambers 5, Figs. l and 2, integral with the rim, and alternating' with the spokes 6, as shown in Fig. -1. The tire sheath 2 isl furnished with the plungers 7, secured to the base thereof and seated in one end of the recesses ofthe spring chambers 5. The heads of the spring chambers are furnished with the threaded tension bolts 8 the ends of which within the spring chambers are prvided with the heads 9,. Between the plungers 7 and the heads 9 are coiled the sprin s 10.v l

Re errihg now to Fig. 2 it will be seen'that the tire 1, when not under pressure, is maintained by the ex ansiveA action of the spring in the position t ere shown.

If pressure be now applied to the tread of the tire andinward movement toward the wheel hub takes place at that point, the neck of the tire sheath 2- sliding between the jaws of the rim, the base `ofthe tire Vsheath moving downward toward the base of the wheelrim and the plunger 7 descending into the spring chamber. This-play of the tire within the aws of'- the wheel rim may be controlled in its extent b y the degree of lcompression to which the spring 10 is sub'ected by the adjustment of the tension bolt 8.' The tiie is" secured against any' tendency to slide around within the jaws of the rim by the seating of the plunger 7 inthe base of thewheel rim, and

the tire is also held firmly against any tendency to lateral displacementv not only by the seating of the plunger, but also by the man`- ner in? which the tireA is mounted in the aws of the rim.l Forit will be observed that I have theretwo oints of sliding contact and of su port, viz. etween the neck of the tire sheat 1 and the edges of the jaws of the rim, and between the outer sides ofthe enlarged base of the tire sheath andthe inner faces of said aws. Thus the tire, being secured within its sheath by the pins or bolts 3, is proof against any danger of detachment from the wheel rim, whether by lateral strains or by thc'strain incident to the sudden starting or stopping of the automobile.

l To admit of insertion of the tire, tire sheathv and plungers in their place-in the jaws 'and base of the wheel rim the rim is split, as

. shown in Figs. 2 and 3 in cross section and in Fig. l in side view. The removal section of the rim 'thus formed includes of course one jaw of the Wheel rim, fitting to the side of the spring chamber as shown in Fig'. 2 and with an extension bolted to each spoke as shown in Figs. l and 3. The ends ol the spokes may be formed with an offset, as shown at l1, Fig. 3, in order both to reinforce the spoke at that point and to aiiord a face to which the bolted.

,100 removable section of the rim may be securely What I claim as my inventionv and desire to secure by Letters Patent is- In an automobile wheel, a split rim formed with op osing and inwardly: curved jaws, one jaw cing integral with the wheel spoke and the other jaw being removably secured to said wheel s oke, a spring chamber recessed in said vs -it rim and formed partly in the integral anrlpartly in the removable javir thereof, a tire having an enlarged tread and" A base and a narrowed neck, a. tire sheath sesprng may be regulted, substantially as decured to and inclosng the neck and base og scribed. said tire, a ungel secured to said tire sheat and sldab y mounted in said spring cham- WILLIAM MULLER' 5 ber, a sprlng coiled in said spring chamber, Witnesses:
